Greetings,

I am having an odd problem with a number of extensions. They will ring when dialed but cannot be answered by picking up the receiver.
They can only be answered by hitting the SPEAKER button.

There is no dial tone heard in the receivers either.

I have swapped in a known good phone and am having the same behaviour.
I have also defaulted the offending extnensions.
This worked but only briefly. (Which is weird.)

Any help would be most appreciated.

Regards
